Roller Coaster, Carnival and; Amore builds - please post your pics

I put my KPST roller coaster on a 50x50 lot and found that a challenge. I think I started on a 40x40 and abandoned it. 40x40 is possible if you want a small track and nothing much by way of extra fun things for Sims to do.

I might try it eventually. I am rushing to get this latest one finished so I can start on the next one. I already have another one partly made - the track is valid but I've done nothing else. I don't know if I'll ever get back to that one though. It might just be a big delete.
